The Luna release has reached SR2, OCL 5.0.4, so further bug fixes, if
any, will be trivial.
The OCL CG is steadily improving and so you should find quite a few
fixes in Mars M6 (this evening) and it is not too late for bugs to be
fixed for Mars. So I recommend you use the latest code and contribute to

> maybe someone could help me with a problem that I have when trying to generate Java code for static UML profiles. At the moment, I try to migrate a UML profile to Eclipse Luna. The profile defines a lot of OCL invariants and queries in the context of its stereotypes. Many constraints makes use of 'base_xxx' and 'extension_yyy' associations. My current profile implementation for Eclipse Kepler uses a customized OCL evaluation environment that makes such navigation possible. Due to performance reasons, for the Luna Edition I would like to generate native Jave code for all kind of OCL invariants and queries. But unfortunately OCLinEcore crashes during code generation for my profile with the following NPE.
